Dynamic performance of industrial robot in corner path with CNC controller

The industrial robot has already been used for machining tasks in the industry. In order to improve the machining accuracy, a CNC controller is proposed as a control system for the industrial robot. This article concentrates on the performance of the industrial robot motion accuracy guided by a CNC controller. Corner paths are studied in consideration of different running speeds. The path accuracy and the influence of motion acceleration are both thoroughly analyzed. The performance of the same paths running in a conventional controller is evaluated for comparison.
